First Claim
Patent Images
1. A system for acquisition of mapping data, comprising:
- a sensor that outputs sensor data related to a position of a catheter;
a mapping system that receives said sensor data and computes a catheter actual position;
a user control device that produces a user control output related to a desired position;
a motion module that computes a plurality of modified desired positions based on said desired position; and
a closed-loop control system that receives said actual position and said plurality of modified desired positions and produces output control data that is provided to a position control system, said position control system moving a physical position of said catheter according to said output control data, said output control data configured to move said catheter to each of said modified desired positions, said mapping system configured to produce a map of a body cavity using catheter actual positions corresponding to each of said plurality of modified desired positions.

Abstract
The invention is a method of rotating a catheter while it is manually guided in order to increase the volume of space it passes through during a geometric mapping procedure as to provide a higher and more uniform location data point cloud density in a volumetric mapping system.
